"Some relays are constructed with a kind of “shock absorber” mechanism attached to the armature which prevents immediate, full motion when the coil is either energized or de-energized. This addition gives the relay the property of time-delayactuation. Time-delay relays can be constructed to delay armature motion on … Ver mais First, we have the normally-open, timed-closed (NOTC) contact.
